1. Remove the roof console box assembly.

2. Measure the resistance according to the value(s) in the table below.

   Standard resistance:

   Tester Connection	Switch Position	Specified Condition
   Q6-1 (CLS) - Q6-3 (GND)	CLOSE	Below 100 Ω
   Q6-2 (OPN) - Q6-3 (GND)	OPEN	Below 100 Ω
   Q6-4 (DOWN) - Q6-3 (GND)	DOWN	Below 100 Ω
   Q6-5 (UP) - Q6-3 (GND)	UP	Below 100 Ω
   Q6-1 (CLS) - Q6-3 (GND)	OPEN	1 kΩ or higher
   Q6-2 (OPN) - Q6-3 (GND)	CLOSE	1 kΩ or higher
   Q6-4 (DOWN) - Q6-3 (GND)	UP	1 kΩ or higher
   Q6-5 (UP) - Q6-3 (GND)	DOWN	1 kΩ or higher

OK	Go to step 10

NG

1. Temporarily replace the roof console box assembly (sliding roof control switch) with a new one or normally functioning one (Click here).
